Hi Ed,
I've been to the November 2007 TCFF Experience and I can assure you, it is fantastic! We had about 6 people in our group if I remember correctly. That group spends the day with a different guide for each day of the experience.
This article may also help you to get an idea of what it's like. It is definitely worth it to go to this World Class venue.
Kind regards,
PTN
